I'm getting oversupply warnings on my routes to Osaka since the changeover from ITM to KIX, even though I wasn't even supplying 100% of demand at ITM. But it's only on routes to two of my bases (SDJ and HND). Demand to my HQ at CTS remains about what it was at ITM.
For SDJ, the demand is about 15% of what it was before. SDJ-ITM had demand around 1200/day. Now it's 200/day. It was a highly competitive route between myself and Sayonara Air, whose base transferred from ITM to KIX. (I'd hate to see how much of a mess he's in now!)
For HND, I'm not getting oversupply warnings since I'm now at 100% supply HND-KIX, but for HND-ITM I was supplying less than 20% of demand.
Shouldn't the demand remain fairly constant between the old and new airport considering it's an outright replacement and not a 2nd airport?
